Toxicological Expertise for Biotech

Tox by Design offers a range of toxicological expertise to ensure the safety and efficacy of your pharmaceutical and chemical biotech products.

Specifically, we provide consulting services for biotech companies during the industrial implementation of New Chemical Entities and New Biological Entities with:

  • Toxicological Risk Assessment
  • Toxicological Evaluation


Toxicological Risk Assessments

Any new chemical or biological entity being developed will require Health Based Exposure Limit (HBEL) documentation, such as Occupational Exposure Limit (OEL) or Permitted Daily Exposure (PDE) assessments in order to begin manufacturing. 

Tox by Design provides expertise that can assist you by:

  • Calculating a temporary HBEL using in-silico (QSAR) results
  • Updating your HBEL as toxicology study results become available

During New Chemical Entity (NCE) or New Biological Entity (NBE) development:

  • Developing and updating  OELs, PDEs and SDSs package


Toxicological Evaluation

Any chemical impurities discovered during the development of a new chemical or biological entity have to be qualified. The guidance for identification, categorization, qualification and control of impurities is provided by the ICH guidelines Q3A/B, Q6 A/B, M3 and M7.

Tox by Design experts will help you with every step of your mandatory ICH impurity report. We can also provide assistance if you have an impurity that goes out of specification. To learn more about our out of specification services and guidelines, click here.


You can check Tox by Design methodology for PDE Monograph, OEL and SDS which are duly validated and signed by an European Registered Toxicologist expert.

In the event you are performing this exercise for innovative compounds GMP scale up manufacturing, please be noted that Tox by Design is duly accredited for the French Research Tax Credit CIR.
